Uranium in Pegmatites - GeoScienceWorldUranium and rare-earth minerals are common accessory minerals in pegmatite deposits. No domestic pegmatites have been found that are rich enough to support an economic mining operation for uranium alone; how- ever, small quantities of uranium minerals may be recovered as by-products of feldspar or mica mining.mining pegmatites for rare earth minerals,Prospecting for Rare Earth Metals - ICMJ's Prospecting and Mining .The next most important rare earth mineral is monazite. It is a yellow-brown phosphate of the rare earths and thorium, with a formula of roughly (Ce,La,Y,Th)PO4. It occurs as an accessory mineral in alkaline crystalline rocks such as granites, gneisses, aplites and pegmatites. Because it is resistant to chemical weathering,.

In the few deposits examined the rare earth minerals-cerite, euxenite, samarskite, monazite, and allanite-are distributed erratically throughout feldspar-rich cores in pegmatites that commonly contain only small quantities of muscovite. No rare earth minerals occur in deposits large enough to be mined for them, but a small.
A rare-earth mineral contains one or more rare-earth elements as major metal constituents.
